Fuel pumps work by pressurizing the fuel and sending it to the engine. A low fuel level can cause the engine to work much harder to build the necessary pressure to pump the fuel. To analyze the problem, start the car when the fuel is low (below one-fourth tank) and listen for the sound. If the whine is audible, fill the tank immediately. When you start the vehicle again, the whine should be reduced or absent. If not, there may be another problem.
The whining noise may be caused by a damaged fuel pump. The fuel pump may be punctured or dented, reducing its efficiency. To resolve this issue, the fuel tank must be accessed and repaired or removed. The location of the fuel tank depends on the construction of the vehicle. In a vehicle equipped with a carburetor, the fuel pump is often located outside of the fuel tank. With a vehicle that has a fuel injector, the fuel pump is located inside of the tank. It is best to get a mechanic to address this problem.
